What actually is the Register mode?

You should really have here LED_COLOR_ID_MOONLIGHT if this is
a moonlight LED. You'll need to add it to dt-bindings/leds/common.h.

It is of little avail to have multicolor LED with only two LEDs.
I propose not to allow such setup - i.e. you should have either
one multicolor LED comprising three sub-LEDs (regs: 0, 1, 2),
and with main color property set to LED_COLOR_ID_RGB, or three separate
LEDs.
Effectively, you should have two separate DT examples here to make it
clear: one for the case with three LED class devices and one with
LED multicolor class device.
